DE-AERATOR.

' Specification of Letters Patent.

Patented Sept. 9, 1913.

Application filed January 10, 1913. Serial N 0. 741,288.

To all whom it may concern:

Be it known that I, FRANK S. STRITE, a citizen of the United States,residing at Dallas, in the county of Dallas and State of Texas, haveinvented certain new and useful Improvements in De-Aerators, of whichthe following is a specification, reference being had to theaccompanying drawings.

This invention comprehends certain new and useful improvements in waterde-aerators, and has for its primary object to. provide a device whichwill thoroughly separate the air from the water.

It isa well known fact that air and gases mix with water as it is drawnfrom the ground and exposed to the atmosphere.

When the water is to be employed in the manufacture of ice and for otherpurposes, the air and gases should be separated therefrom, and for thispurpose I have constructed a deaerato'r of novel form and which will behighly eflicient and elfective in the performance of its duty.

My invention consists in providing a tank with a perforated cylindertherein, means for forcing the water into the, tank and spraying thesame against-the cylinder to cause the air and gases to separate fromthe water, and means for causing a vacuum in the upper end of the tankfrom which a suction pipe extends to allow ready escape of the separatedair and gases.

The construction, combination, formation and arrangement of the parts ofthe deaerator will be hereinafter more fully described, claimed, andparticularly pointed out in the accompanying drawings, in which Figure 1is a diagrammatic view of my device. Fig. 2 is a vertical longitudinalsection throu h the tank and perforated cylinder, cleafiy showing theparts thereof.

Referring more particularly to the drawings, in which similar referencecharacters designate corresponding parts throughout the several views,the numeral 1 designatesthe tank having the removable lower portion 2carrying the supportlng legs 3, and secured along 1ts upper edge to thelower edge of the tank 1 by the rivets 4:, or other suitable means. Theremovable lower portion 2 carries the inwardly directed inner flange 5near its upper edge, upon which flange 5 rests the lower edge of theperforated cylinder 6, which may be formed of a wire mesh, or otherforaminous material. The removable lower section 2 forms a chamber forthe de-aerated or purified water, and has a drain opening 7 in thebottom thereof with the plug 8 removably secured therein. The outletpipe 9 has one end secured in the side of the removable lower portion 2,by means of which the water may be withdrawn from the section or chamber2. The upper edge of the cylinder 6 is spaced some distance from theupper end of the tank 1 and said tank is pro-- vided in the side thereofadjacent the upper end w1tl1 an opening 10 through which the supply pipe11 is secured, suitable bushing 12 being placed around the pipe 11 atthe point at which it enters the cylinder to form a water and air-tightconnection. The outer end of the supply pipe 11 is connected with thecentrifugal pump 13 which is operated by the motor 14:, or any othersuitable means to force the water to be purified into the tank 1, bymeans of the pipe 11, under pressure, as will be clearly understood.

The inner end of the pipe 11, within the tank 1, is turned downwardly,as shown at 15, within the cylinder 6, the lower ex; tremity of the pipe15 terminating slightly above the lower end of the cylinder. The pipe 15is provided with the radially di rected arms 16 within the cylinder 6,said arms 16 being shown as arranged in pairs, although any number ofarms may be provided. The arms 16 are provided with caps 17 upon theirouter ends and the small perforations 18 in thesides thereof, and extending the entire length of said arms.

The upper end of the tank 1 is provided with the outwardly directedflange 19, upon which is secured the flange edge 20 of the removable top21, by means of the bolts 22, or the like. Secured in the removable top21 is one end of an air suction pipe 23, the

opposite end of which connects with a vacuum pump 24, operated by themotor 25, or other suitable power. The suction pump 24- creates a vacuumin the upper end of the tank 1 and draws the air and gases from the tank1 as said air and gases separate from the water forced out of the smallperforations 18 in the arms 16, the water finding its way to the lowerremovable section or chamber 2, as will be clearly apparent. By means ofthe construction described above, and clearly shown in the drawings, itwill be apparent that the impure watercontaining air and gases, will beforced through the pipe 11 and through the small perforations 18 of thearms 16 projecting from said pipe 11, under high pressure, causing thewater with the air and gases to be forced out of the arms 16 and againstthe cylinder 6, in the form of a fine spray, thus causing the air andgases to separate from the water. The separated air and gases will bereadily drawn out of the upper end of the tank 1 by way of the airsuction pipe 23 while the small globules of water will find their way tothe removable section or chamber 2 from which the same may be withdrawnby means of the outlet pipe 9. The removable section or chamber 2 may bereadily drained when occasion may require by removing the plug 8.

It will be understood that while I have shown the preferred form of myinvention, minor changes in the details of construction may be made, andany form of centrifugal pump, or other means may be employed for forcingthe Water through the pipe 11 and the arms 16 thereof, and anyconstruction of vacuum pump, or other means may be employed for drawingthe air and gases from the tank 1.

It will be understood that as the perforations 18 in the arm 16 are verysmall and the impure water is forced through these openings under highpressure, the water will be separated into extremely small or minuteparticles before coming in contact with the perforated cylinder 6, thusfreeing the air and gases from the water and allowing ready escape ofsaid air and gases, as previously described.

What is claimed is l. A device of the class described comprising asupply pipe having radially directed arms, said arms being closed attheir free ends and having perforations extending longitudinallythereof, a perforated cylinder surrounding the "arms, a tank inclosingthe arms and cylinder, means for forcing water through the pipe and outof the perforations of the arms under pressure to cause air and gases toseparate from the water, a water chamber at the bottom of the tank, and

ing into the tank above the cylinder, the I inner end of the pipe beingdirected downwardly, radially extending arms carried by the inner endofthe pipe within the cylinder, said arms being provided along theirsides with small perforations, means for closing the outer ends of thearms, means for forcing water containing air and gases through thesupply pipe and out of the perforations of the arms of said pipe .tocause the air and gases to separate from the water, and means forwithdrawing the air and gases from the tank.

3. A device of the class described, comprising a tank, a cylinder Withinthe tank, the lower end of the tank being removable and forming a waterchamber, means carried by the removable lower end of the tank forsupporting thecylinder, a supply pipe depending within the cylinder, theupper end of the cylinder being spaced from the upper end of the tank,the supply pipe entering the chamber above the cylinder, rearwardlyextending arms carried by the lower end of the pipe and provided withperforations in opposite sides, means for forcing water throu h the pipeand within the perforations in t e arms and against the cylinder tocause air and gases to separate from the water, the latter finding itsWay to the water. chamber, an outlet pipe projecting from the waterchamber, and means removably connected with the upper end of the tankfor withdrawing the separated air and gases.

In testimony whereof I hereunto afiix my signature in the presence oftwo witnesses.
